GLSA-202210-12 : Lighttpd: Denial of Service
Discription

The remote host is affected by the vulnerability described in GLSA-202210-12 (Lighttpd: Denial of Service)

– In lighttpd 1.4.65, mod_wstunnel does not initialize a handler function pointer if an invalid HTTP request (websocket handshake) is received. It leads to null pointer dereference which crashes the server. It could be used by an external attacker to cause denial of service condition. (CVE-2022-37797)

– A resource leak in gw_backend.c in lighttpd 1.4.56 through 1.4.66 could lead to a denial of service (connection-slot exhaustion) after a large amount of anomalous TCP behavior by clients. It is related to RDHUP mishandling in certain HTTP/1.1 chunked situations. Use of mod_fastcgi is, for example, affected.
This is fixed in 1.4.67. (CVE-2022-41556)
